运行一段时间后程序崩溃的问题

just-in-time (JIT) debugging instead of this dialog box.

************** Exception Text **************

硬盘空间明明还有几个G空间。
怀疑是TextBox内消息太多，没有清除的原因。
private void ShowMsg(string msg)
{
     if (txtWorkingBoard.Lines.Length > 3000)
         txtWorkingBoard.Clear();
     txtWorkingBoard.AppendText(msg);
}
加上该判断后，到目前为止还没有崩溃。
